刀具状态监测的目的是为了开发出实用的刀具状态监测设备,为了降低设备成本和提高监测的准确率,在监测信号的选择和特征提取的基础上,选择合适的模式识别方法至关重要。对近年来在学术期刊上公开发表的关于刀具磨损在线监测研究中所采用的主要模式识别方法作了简要的回顾与归纳,为后续研究者的快速入门及选择适当的模式识别方法提供参考。 The purpose of tool condition monitoring is to develop a practical tool condition monitoring equipment. In order to reduce the equipment cost and improve the monitoring accuracy, it is very important to select the appropriate pattern recognition method based on the selection of monitoring signals and feature extraction. In this paper, we briefly review and summarize the main pattern recognition methods used in the on-line monitoring of tool wear published in academic journals in recent years, and provide a reference for follow-up researchers to quickly get started and select appropriate pattern recognition methods.
